It really depends on the cat. I have several Persians. I have one who's adult weight is 6.2 lbs, one who is 7.3, one's 8, one's 9.5 lbs and then Chelsea who is 11 lbs.None are overweight. Just built differently. The 3 largest have the same mother and father and they are all still different. But a female persian shouldn't get any bigger than my Chelsea who is 11 pounds.
